I am trying to define a method (called a "range") that returns an array. I pass two integers, for example m and n, and return an array of length (nm), as described in the following listing: I assume that n is greater than m. But I would like to impose this condition explicitly. Is there any way to impose such conditions on method arguments?
You can suggest me changing the method to pass m and (nm) instead of m and n into the method, but it still assumes that nm is a positive integer. Therefore, we need to find a way to impose these types of constraints on method arguments.
public static int[] range(int m, int n) {
int[] r=new int[n-m];
for(int i=0; i<n-m; i++)
r[i]=m+i;
return r;
}
